The C172 has the advantage, in that it is much lighter, but has about the same load bearing as the Warrior. My heart rose when I figured out that, in terms of weight, I could take off with 2 * 13 Stone adults in the front, 2 * 11 Stone adults in the back, 28 lbs of baggage, and a half tank of fuel... just.
My heart promptly sank when the C of G was way aft of the limit (38.5" at full weight is the limit, and I had calculated the above load at 44").
Further to 18greens' comment. Are you sure about the aft limit? I'm assuming your comment is for the 172. The one I fly (a 172SP) has an aft limit around 47" (IIRC). Obviously it depends upon the datum used. The same loading you suggest puts me slightly overweight but the CG is well within limits (obviously with a different basic weight and CG to your aircraft but CG is unlikely to be vastly different). This is for the normal category, utility is going to be somewhat more limited.
